Hedge grammars have really nice features, which can be parsed by a class of pushdown automata. However, my experience is that not many people understood and valued those features in the XML ecosystem (see SVG but also Xpath). Would be nice to see actually a schema first language that has a good binary and human readable representation. IMHO we can do better than zipped JSON even if is hard.
